ATENT FLO-ATING LOCK.

SPECIFICATION forming partof Letters Patent No. 423,561, dated March 18, 1890.

Application filed October 26, 1889- I refer to the accompanying drawings, in

which similarletters denote similar parts throughout the several views.

Figure 1 is a view in ers ective of 1n floating lock. Fig. 2 is a sectional elevation of the same. Fig. 3 is a cross-section of the lock. Fig. 4 is a cross-section of the well. Fig. 5 is a top view of the lock on its floating cylinder. Fig. 6 is a vertical section showing the mechanism for closing the orifices ff drawn to a larger scale. Fig. 7 is a plan of the lever-arm for operating the cover. Fig. 8 is a sectional view of` the orifice with the cover closed on a still larger scale.

This iioating lock is for use in canals where the difference of water -level between the reaches is so great that an ordinary lockchamber is not sufficient for the transport ol"l a vessel from one reach to the other.

In the perspective view of the lock shown in Fig. l, A is the lower and B the upper reach, and C is the lock-chamber, which is raised and lowered in the manner hereinafter described. At each end of the lock-chamber, as also at the ends of the upper and lower reaches, arelock-gatesp and p, which maybe opened.

. If a vessel passes from Ato B, the lock-chamber is placed on a level with the lower reach,

and after the gates p have been opened and the ship admitted into t-he lock-chamber the gates will be closed again.l The lock-chamber is now raised and the upper gates opened, when the ship will belet out and can proceed farther. The process is pretty much the same when a vessel passes from B to A.

Referring to Figs. 2 and 3, D is awell illed with water up to line g h. E is an empty water-tight iron drum, the upper end of which is shown in Fig. 2 by a dotted'line a b. F is a cylinder connected with drum E, and into which the water of welll) may be driven Serial No. 328,223. (No model.)

through openingsff. Onthis cylinder, `which has its upper end open, the lock-chamber C rests. The cylinder has, however, another purpose hereinafter to be described. The displacementof the drum is sufficient to hold it, the cylinder, and lock-chamber in equilibrium. In consequence these three parts remain floating. These three parts are all guided vertically up and down. As may be seen in Fig. 4, two guiding-claws c c are attached to the outside of drum E which slide on guiding-rods d, Figs. 2 and 3, running down the sides of the well. Further, two guidingblocks e e, Fig. 3, are attached to the upper part of the cylinder or under the lock-chamber, which said blocks run on guides supported in trestles G G. A

Fig. 5 shows a plan of the cylinder with its guide-blocks c e. The whole, consisting of drum, cylinder, and ilock-chamber, isthus guided vertically, and it only remains to remark that the vertical guides may be supported by brick-work piers instead of iron truss-work, as shown in the drawings. The

openings f f in the cylinder may be closed,

and when the drum, with its cylinder and lock-chamber, is in a state of rest they are closed. On raising the lock-chamber water flows out of the cylinder into the Well through the openings f f, which have then been opened, while in sinking the lock the water flows in the opposite direction. The openings f f may be closed and opened in any convenient manner. One system of effecting this result is shown in Figs. G, 7, and 8 drawn to a larger scale. a b is the cover of the drum; F, the cylinder. The standards 7c are ixed to the cover of the drum, and in these standards the lever vGr has its bearings. The cover P for the opening f is iixed to the end of lever G. Lever G may be operated by a. chain fn. Orifice j' is provided with an india-rubber ring, on which the cover closes. As, however, the lever and cover are tolerably heavy, it is advisable to introduce -some motive power for operating the Same. In the drawings hydraulic power is intended, waterv being pumped into the cylinder l underneath the pose. CylinderZ is supported on iron guides' IOO m m. The Working of the cover may, however, be effected in any other suitablel manner, asnthe particular mechanism connected with this arrangement is not involved in the present invention.

In the upper part ik of the well, Figs. 2 and 3, the walls of the cylinder are thrown forward, projecting nearer to the sides of the cylinder, thus diminishing the annular space between cylinder and well. sary that this space should be made watertight, and the water-level in the well stands atthe same height as in the cylinder, or the variation is only slight. If now the lockchamber is filled with suflicient water to overcome the'displaeement of the drum, the Wa ter-level in the annular space between well .and cylinder will stand higher than that in the cylinder, (assuming the openings ff of the cylinder to be closed,) and vice versa when the chamber contains less water t-han'necessary to. overcome displacement of drum. The annular space between well and 'cylinder is therefore diminished in order that the variation in the height of the lock-chamber may remain slight when the saine is more o r less loaded with water. Toward the lower part a widening of the well, asin Figs. 2 and 3, may

r be introduced with advantage,as in this case that necessary to balance the displacement of l the drum on the gates p being opened, and

'consequently Weight enough is present in the lock-chamber to overcome the'displacement It is not neces' of the drum and effect the earlier or later de-K Fontinettes and la Louvire, in France andV Belgium. f l

I reserve to myself the right of using two cylinders and Wells inthe manner of the one described-for instance, in the case of big lock-chambers.

Having thus fully described the 'nature of my said invention, what I desire to secure by Letters Patent of the United States is- 1. A floating lock, substantially as herein' described, consisting, principally, of a drum, a cylinder resting on the same, and lock-chamber resting on the cylinder, which three parts are together guided/vertically and floatv in a well, the top of the wall of which projects inward close to the sides of the cylinder, so that no water-tight sealing of the well is necessary.

2. The cylinder restingv upon the drum and provided with the openings atA the bottom of its sides, which openings may be closed or opened, whereby the stoppage or regulation of the motion of the lock-chamber, cylinder, and drum, constituting one Whole piece, may be eected.

In witness whereof VI have hereunto set my l hand in presence of two witnesses.
